I am moving my 5 gallon QT tank and my 5 gallon shrimp tank to near ground level onto stands that will house my 20 gallon long and 10 gallon on the upper shelves of the stands. At near ground level it will not be possible to siphon water. Can anybody recommend a small pump that I can use to evacuate water from these two tanks? I can obviously be a very simple pump. Thanks.
